Seven people were shot and killed in Chicago on Saturday alone. Among the dead: 34-year-old Ronnie Chambers, a former gang member shot in the head as he sat in a car.

(Chambers) "Being in and out of jail, that let me know I had to do something different. So once I told myself that, you know, I need to protect my mother and be out here for her, I told myself I gotta do something else."

Chambers appeared on The Ricki Lake Show last month, at that point the only one of his siblings who had not been killed by gun violence.

(Chambers) "I had two brothers and a little sister. You know, they got killed in Cabrini Greens."

A 16-year-old boy was also killed Saturday, as well as two roommates who were gunned down at a hamburger stand.
